You can use the [inspect][1] module, like this:

    import inspect
    inspect.getfile(C.__class__)


  [1]: http://docs.python.org/library/inspect.html#inspect.getfile

try:

    import sys, os
    os.path.abspath(sys.modules[LocationArtifact.__module__].__file__)

This is the wrong approach for Django and really forcing things.

The typical Django app pattern is:

 - **/project**
    - **/appname**
        - models.py
        - views.py
        - **/templates**
            - index.html
            - etc.

I was wondering how one would find the controls in the HeaderTemplate or FooterTemplate of an Asp.Net Repeater control.

I can access them on the ItemDataBound event, but I was wondering how to get them after (for example to retrieve a value of an input in the header/footer).

Note: I posted this question here after finding the answer just so that I remember it (and maybe other people might find this useful).

Is there any other way besides using [ImageIO.read][1] to get image height and width?

This error only occurs on a Sun app server and therefore I suspect that it is a Sun bug.

Given a class C in Python, how can I determine which file the class was defined in? I need something that can work from either the class C, or from an instance off C.

The reason I am doing this, is because I am generally a fan off putting files that belong together in the same folder. I want to create a class that uses a Django template to render itself as HTML. The base implementation should infer the filename for the template based on the filename that the class is defined in.

Say I put a class LocationArtifact in the file &quot;base/artifacts.py&quot;, then I want the default behaviour to be that the template name is &quot;base/LocationArtifact.html&quot;.

If I keep calling len() on a very long list, am I wasting time, or does it keep an int count in the background?

I have a string containing text and HTML. I want to remove or otherwise disable some HTML tags, such as `&lt;script&gt;`, while allowing others, so that I can render it on a web page safely. I have a list of allowed tags, how can I process the string to remove any other tags?

Are there any canned Python methods to convert an Integer (or Long) into a binary string in Python?

There are a myriad of dec2bin() functions out on Google... But I was hoping I could use a built-in function / library.

What is the best way to choose a random file from a directory in Python?

*Edit:* Here is what I am doing:

    import os
    import random
    import dircache

    dir = &#39;some/directory&#39;
    filename = random.choice(dircache.listdir(dir))
    path = os.path.join(dir, filename)

Is this particularly bad, or is there a particularly better way?

Python&#39;s inner/nested classes confuse me. Is there something that can&#39;t be accomplished without them? If so, what is that thing?

What is the purpose of python&#39;s inner classes?

I am not sure if this is possible but I want to iterate through a class and set a field member property without referring to the field object explicitly:

    public class Employee
    {
      public Person _person = new Person();
    	
      public void DynamicallySetPersonProperty()
      {
        MemberInfo[] members = this.GetType().GetMembers();
    
        foreach (MemberInfo member in members.Where(a =&gt; a.Name == &quot;_person&quot;))
        //get the _person field
        {
    
          Type type = member.GetType();
          PropertyInfo prop = type.GetProperty(&quot;Name&quot;); //good, this works, now to set a value for it
    
          //this line does not work - the error is &quot;property set method not found&quot;
          prop.SetValue(member, &quot;new name&quot;, null);
        }
      }
    }
    
    
    public class Person
    {
      public string Name { get; set; }
    }



In the answer that I marked as the answer you need to add:

      public static bool IsNullOrEmpty(this string source)
      {
        return (source == null || source.Length &gt; 0) ? true : false;
      }

I want to have a Class object, but I want to force whatever class it represents to extend class A and implement interface B.

I can do:

    Class&lt;? extends ClassA&gt;

Or:

    Class&lt;? extends InterfaceB&gt;

but I can&#39;t do both.  Is there a way to do this?

How can I get a list (in the form of an `NSArray` or `NSDictionary`) of a given object properties in Objective-C?  

Imagine the following scenario: I have defined a parent class which just extends `NSObject`, that holds an `NSString`, a `BOOL` and an `NSData` object as properties. Then I have several classes which extend this parent class, adding a lot of different properties each.  

Is there any way I could implement an instance method on the *parent* class that goes through the whole object and returns, say, an `NSArray` of each of the (child) class properties as `NSStrings` that are *not* on the parent class, so I can later use these `NSString` for KVC?

I&#39;m starting to code in various projects using Python (including Django web development and Panda3D game development). 

To help me understand what&#39;s going on, I would like to basically &#39;look&#39; inside the Python objects to see how they tick - like their methods and properties. 

So say I have a Python object, what would I need to print out its contents? Is that even possible?

I&#39;ve a Java object &#39;ChildObj&#39; which is extended from &#39;ParentObj&#39;. Now, if it is possible to retrieve all the attribute names and values of ChildObj, including the inherited attributes too, using Java reflection mechanism?

[Class.getFields][1] gives me the array of public attributes, and [Class.getDeclaredFields][2] gives me the array of all fields, but none of them includes the inherited fields list.

Is there any way to retrieve the inherited attributes also?

Retrieving the inherited attribute names/values using Java Reflection

Suppose `myapp/foo.py` contains:

    def info(msg):
        caller_name = ????
        print &#39;[%s] %s&#39; % (caller_name, msg)

And `myapp/bar.py` contains:

    import foo
    foo.info(&#39;Hello&#39;) # =&gt; [myapp.bar] Hello

I want `caller_name` to be set to the `__name__` attribute of the calling functions&#39; module (which is &#39;myapp.foo&#39;) in this case. How can this be done?
